Evaluation of commercial utility of ERTS-A imagery in structural reconnaissance for minerals and petroleum

Five areas in North America (North Slope-Alaska, Superior Province-Canada, Williston Basin-Montana, Colorado and New Mexico-West Texas) are being studied for discernibility of geological evidence on ERTS-1 imagery, Evidence mapped is compared with known mineral/hydrocarbon accumulations to determine the value of the imagery in commercial exploration programs. Evaluation has proceeded in the New Mexico-West Texas area while awaiting imagery in the other areas. To date, results have been better than expected. Clearly discernible structural lineaments in New Mexico-West Texas are evident on the photographs. Comparison of this evidence with known major mining localities in New Mexico indicates a clear pattern of coincidence between the lineaments and mining localities. In West Texas, lineament and geomorphological evidence obtainable from the photographs define the petroleum-productive Central Basin Platform. Based on evaluation results in the New Mexico-West Texas area and on cursory results in the other four areas of North America, ERTS-1 imagery will be extremely valuable in defining the regional and local structure in any commercial exploration program

ERTS-1 imagery use in reconnaissance prospecting: Evaluation of commercial utility of ERTS-1 imagery in structural reconnaissance for minerals and petroleum

The author has identified the following significant results. This study was performed to investigate applications of ERTS-1 imagery in commercial reconnaissance for mineral and hydrocarbon resources. ERTS-1 imagery collected over five areas in North America (Montana; Colorado; New Mexico-West Texas; Superior Province, Canada; and North Slope, Alaska) has been analyzed for data content including linears, lineaments, and curvilinear anomalies. Locations of these features were mapped and compared with known locations of mineral and hydrocarbon accumulations. Results were analyzed in the context of a simple-shear, block-coupling model. Data analyses have resulted in detection of new lineaments, some of which may be continental in extent, detection of many curvilinear patterns not generally seen on aerial photos, strong evidence of continental regmatic fracture patterns, and realization that geological features can be explained in terms of a simple-shear, block-coupling model. The conculsions are that ERTS-1 imagery is of great value in photogeologic/geomorphic interpretations of regional features, and the simple-shear, block-coupling model provides a means of relating data from ERTS imagery to structures that have controlled emplacement of ore deposits and hydrocarbon accumulations, thus providing a basis for a new approach for reconnaissance for mineral, uranium, gas, and oil deposits and structures

Immune cells and preterm labour:do invariant NKT cells hold the key?

We have developed our original made-to-measure (M2M) algorithm, PRIMAL, with the aim of modelling the Galactic disc from upcoming Gaia data. From a Milky Way like N-body disc galaxy simulation, we have created mock Gaia data using M0III stars as tracers, taking into account extinction and the expected Gaia errors. In PRIMAL, observables calculated from the N-body model are compared with the target stars, at the position of the target stars. Using PRIMAL, the masses of the N-body model particles are changed to reproduce the target mock data, and the gravitational potential is automatically adjusted by the changing mass of the model particles. We have also adopted a new resampling scheme for the model particles to keep the mass resolution of the N-body model relatively constant. We have applied PRIMAL to this mock Gaia data and we show that PRIMAL can recover the structure and kinematics of a Milky Way like barred spiral disc, along with the apparent bar structure and pattern speed of the bar despite the galactic extinction and the observational errors

Inter-species horizontal transfer resulting in core-genome and niche-adaptive variation within Helicobacter pylori

Background Horizontal gene transfer is central to evolution in most bacterial species. The detection of exchanged regions is often based upon analysis of compositional characteristics and their comparison to the organism as a whole. In this study we describe a new methodology combining aspects of established signature analysis with textual analysis approaches. This approach has been used to analyze the two available genome sequences of H. pylori. Results This gene-by-gene analysis reveals a wide range of genes related to both virulence behaviour and the strain differences that have been relatively recently acquired from other sequence backgrounds. These frequently involve single genes or small numbers of genes that are not associated with transposases or bacteriophage genes, nor with inverted repeats typically used as markers for horizontal transfer. In addition, clear examples of horizontal exchange in genes associated with 'core' metabolic functions were identified, supported by differences between the sequenced strains, including: ftsK, xerD and polA. In some cases it was possible to determine which strain represented the 'parent' and 'altered' states for insertion-deletion events. Different signature component lengths showed different sensitivities for the detection of some horizontally transferred genes, which may reflect different amelioration rates of sequence components. Conclusion New implementations of signature analysis that can be applied on a gene-by-gene basis for the identification of horizontally acquired sequences are described. These findings highlight the central role of the availability of homologous substrates in evolution mediated by horizontal exchange, and suggest that some components of the supposedly stable 'core genome' may actually be favoured targets for integration of foreign sequences because of their degree of conservation

Reason and Emotion, Not Reason or Emotion in Moral Judgment

One of the central questions in both metaethics and empirical moral psychology is whether moral judgments are the products of reason or emotions. This way of putting the question relies on an overly simplified view of reason and emotion as two fully independent cognitive faculties whose causal contributions to moral judgment can be cleanly separated. However, there is a significant body of evidence in the cognitive sciences that seriously undercuts this conception of reason and emotion, and supports the view that moral judgments are caused by a complex interplay of psychological mechanisms that are both cognitive and affective, but in a way that is not simply a function of the independent causal contributions of reason and emotion. The paper concludes by considering the implications of this view for metaethics

B571: Contract Broiler Growing in Maine

The Maine broiler industry had its beginning in the late 1920s and early 1930s with the greatest development occurring after World War II. Live poultry buyers, who later became processors, were the originators of the industry and have played the leading role in its development. Processing and broiler production along with hatching egg production and hatchery operations are vertically integrated to a relatively high degree in Maine. Broiler production in Maine has continued to increase at a more rapid rate than broiler production in the entire United States. By 1957 broiler production in Maine had reached 50 million birds which amounted to 3.5 per cent of total U. S. broiler production, making Maine the 10th ranking broiler state. The findings from this study of contract broiler growing in Maine indicate that carefully planned, vertical integration by processors is a sound method of cost reduction and quality control. Furthermore, contract broiler growers generally are satisfied with their arrangements for growing broilers and prefer the contract system to growing broilers independently.https://digitalcommons.library.umaine.edu/aes_bulletin/1032/thumbnail.jp

The Necessity of Moral Reasoning

A new variety of empirical skeptical moral arguments have been put forward in recent years, drawing on data from neuroscience, social and behavioral psychology, and economics, which strongly suggest that emotions play a central causal role in moral judgment, and that reasoning has at most a limited supplementary causal role in small portion of moral judgments. It follows from these empirical finding, it is argued, that moral judgments and morality more generally cannot be grounded in reason in the right sort of way to be rational. I argue that there are at least three distinct ways of understanding what it means to claim that moral reasoning is necessary to moral judgment. First, that moral reasoning is directly causally necessary to every moral judgment; second that moral reasoning is causally necessary to the ordinary development of the capacity for moral judgment, but is not directly causally implicated in every particular instance of moral judgment; and third that moral reasoning is necessary to a well-ordered capacity for moral judgment. I argue that the empirical data does support the claim that reasoning is not necessary to moral judgment in at least the first sense, perhaps in the second, but not in third, and that this is sufficient to provide for the rationality of moral judgments and morality more generally
